Aim
The study was conducted to determine the prevalence of hydatidosis, to identify the association between expected risk factors and
occurrence of the disease, to investigate economic importance and to evaluate fertility and viability of the hydatid cyst in cattle
slaughtered at the abattoir.
Materials and Methods
A cross-sectional study, which involves both ante-mortem and post-mortem examination, was conducted at Nekemte municipal
abattoir from November 2015 to March 2016.
Results
A total of 355 local cattle breed was randomly sampled and examined for the presence of hydatid cysts in the organs of the animals using the standard meat inspection procedures, 66 (18.6%) animals were found harboring hydatid cysts. Statistical analysis
showed that there was a significant difference (p<0.05) between the prevalence of bovine hydatidosis in all risk factors with exception of sex of the animals. Among 207 hydatid cysts recorded, 93 (44.92%) were from lungs, 65 (31.40%) from livers, 4 (1.93%)
from heart, 3 (1.44%) from kidney, 1 (0.48%) from spleen and 41 (19.8%) were in two organs from lung and liver. Fifty-seven
(57) of these 207 cysts were randomly selected and subjected to fertility and viability test which revealed 19 (33.33%) as fertile,
25 (43.86 %) sterile and 13 (22.81%) calcified. Viability test proved 7 (12.28%) of 19 fertile cysts as viable and 12 (21.05%) of 19
fertile cysts as non-viable. Viability of cysts in different organs revealed that 5 (16.1%) and 2 (10%) of cysts from lungs and liver,
respectively. The estimated financial loss during the study period both due to condemnation of organs and an in direct carcass
weight loss from hydatidosis was 2,190,143.52 ETB.
Conclusion
The results of this study revealed that bovine hydatidosis was an economically important disease of cattle which need serious
attention for prevention and control actions in and around Nekemte. Hence, establishment of well-equipped standardized abattoirs, prohibition of backyard slaughter, creation of public awareness, deworming and control of stray dogs are of paramount
importance.
